Deleted Scene (with Dipper)
Nice article about a deleted scene that was filmed(?) with Apollo doing a PR meeting with Rocky at the Gym, prior to their fight...and Dipper (played by Stan Shaw) the guy who Mickey gave Balboa's locker to, decides to hijack proceedings (replete with stills and original script dialogue)
